This invention has to do with certain new and useful improvements indoor bumpers and the like. The `door bumper constructions hereindisclosed are especially intended for use in connection with the doorsof automobile bodies and the like, although it will appear that saidfeatures mayalso be used to advantage in connection with otherconstructions. Inasmuch, however, as said features 1 have been devisedespecially with a view to meeting the requirements of automobile doors,I have illustrated and will particularly describe such uses andapplications of the invention, but in so doing I Wish it clearlyunderstood that I do not thereby intend to limit myself except as I maydo so in the claims. o

In the construction of automobilebodies it is customary to provide adoor frame member or element against or towards which the edge portionof the door moves during the door closing operation. Usually thiselement is in the form of what is known as a door pillar. The doorpillar is generally so formed as to provide a ledge facing inthedirection Vof* door closing movement and also to provide inwardlyextending flanges lying parallel to the direction of door closingmovement. Generally said pillar is also provided with an outwardlyextending flange which also lies parallel t0 the direction of doorclosing movement.

The companion edge portion of the door is so formed as to providecompanion ledges and flange surfaces; the ledge of the door approachingdirectly towards the ledge of the door pillar, and the flanges of thedoor n1oving parallel to or wiping close to the flanges of the doorpillar. o

It is usually customary to provide one or more bumper blocks on the doorpillar in position to receive the forces of pressure and impact incidentto the door closing opera-` tion. Generally these bumperpblocks on thedoor pillar are provided with head portions which are supported by thedoor pillar or some element thereon and the ledge of the door strikes orpresses against ythe head portion of the bumper block when the door isclosed. The bumper block is also usually Serial No. 563,057.

provided with a lip or skirt portionwhich overlies the inwardlyextending flange at the position of the bumper block and establishes awiping contact surface against which the companion flange surface of thedoor wipes during the door closing movement.

The main object of the present invention is to provide a new andimproved means for securing the bumper block in place on the doorpillar. This securing means is so constituted that the bumper block isheld in place without the need of using any extraneous connectingdevices; the attaching operation being performed by providing the doorpillar and the bumper block with companion openings and lugs whichinterlock with each other to retain the bumper block in place.

More `particularly it is an object of the present invention to providecompanion interlocking openings and lugs on the ledge of the doorplllarand on tne head portion of the bumper block. a further object of theinvention to so arrange the openings of the door pillar ledge that 'theledge is provided with a relatively large and ample dire@J supportingsurface for the head oi' the bumper block so that 'the latter will havean ample support to resist the pressures and shocks incident to the doorclosing operation.

It is a further object of the invention to so relate the parts so thatthe bumper block can be set into and secured in place by the simpleexpedient of bending or deflecting to enable the lugs thereof to beintroduced into the openings of the door pillar, thus eliminating otheroxtr neous connecting devices.

. In some cases it is also an object to provide similar cooperatingopenings and lugs on the p lllar and on the bumper' block for securingthe lip or skirt of the bumper block more permanently in place.

Other objects and uses of the invention will appear from a detaileddescription of the same which consists in the features of constructionand combinations of parts hereinafter described and claimed.

This application is a division of my co- In this connection it ispending application for Letters Patent on improvements in door stops andthe like, Serial No. 527,129, filed April 2, 1921.

In the drawing Figure 1 shows a fragmentary plan view of a short sectionof a door 'pillar having applied thereto a door stop embodying thefeatures ofthe present invention;

"Figure 2 shows a.' cross section'on the lines 2-2 of Figures 1 and 3looking 1n thedlrection of the arrows;

Figure 12 shows a longitudinal section on the line 12-12 of 4Figure V11vlooking -in the direction of the arrows.

The constructions disclosed inFigs. 4, 5, and 8 to 12 formV the subject'matter ofV a separate divisional application, Serial No. 563,055, filedSeptember 16, 1931, and the construction disclosed in Figs. 6 and 7forms the subject matter of another separate divi-V sional application,Serial No. 563,058, filed September 16, 1931. lThis application istherefore confined to the disclosure of Figs. 1 to 3. Y

In each of the constructions herein described and illustrated the,door'pillar is designated in its entirety by the numeral 15. VItincludes the ledge 16 which faces in the 'direction of door closingmovement; and in each instance the door pillar is also provided with theinwardly and outwardly eX- tending flanges 17 and 18 respectively whichlie parallel to the direction-'of door closing movement.

In the construction of Figurevl the bumper block 19 is provided with ahead portion 20 which rests directly upon and is supported by the doorpillar ledge 16. Said bumper block is also provided with a skirt or lipportion 21 lwhich slightly overlies the face por- Vhead portion20 asclearly indicated in F igures 2 and 3. As a consequence this bumperblock can be forced into place, the lugs 24 and 25v snapping orbuttoning through the openings of the door pillar ledge.

It willvbe noted that when this door bumper is in place it is aorded avery large surface of idirect support for the head portion of the bumperblock, the openings through whichl the lugs orbuttons are forced' beingrelatively small.

Preferably also the top or exposed surface of the head of the bumperblock is crowned or. arched as best shown in Figure 3 so that the pointofinitial Contact against the bumper block is directly' between the doorpillar openings. As a consequence there is assurance that the initialand maximum pressure on the bumper block will take place at a pointwhere there is afforded a maximum degree ofv direct support for thebumper block head. l

Referring nextl to the form shownin Figures 4 and 5, in vthis case theledge 16 of the door pillar is so treated as to provide the upwardlystruck llugs or ears 26 and 27 facing eachother and establishing a pairof oppositely' facing openings in the material of the ledge and abovethe surface of the ledge. The ledge materialbetween said openings isuncut and not deformedy between the openings.

In the present case the head portion 28 of the bumper block restsdirectly upon the ledge between said openings; and the end portions ofthe body ofthe head of the bumper block' Vare provided with lugs 29 and30 which can be forced down through the openings in the ledge of thedoor pillar so as to lock the same in place. In the present case alsothe bumper block is provided with a lip or skirt 31 which overlies theedge portion of the flange 17 of the door pillar.

In the construction of Figures 6 and 7 the ledge portion V.of the doorpillar is so treated as to provide the downwardly depressedlongitudinallyy extending seat 32 for directly supporting the headportion 33 of the bumper block, openings 34 and 35'being formed in ltheends "of said ledge portion 32, said openings 34 and 35V facing inopposite directions and beneath the position of the door pillar ledge16. v

In the present case the body portion o-f the bumper block is providedwith the end lugs 36 and 37 which can be forced through said openings tolock the bumper block in place. In the present case also the bumperblock is provided with a lip or skirt 38 which overlies the edge portionof the flange 17.

In the construction of Figures 8 and 9 the ledge portion 16 is sotreated as to provide the downwardly extending lugs or ears 39 and 40which reach to positions below the ledge 16 and face in oppositedirections away from cach other, openings 41 and 42 being thusestablished in the ledge at the position of said lugs or ears 39 and 40.In the present case the material of the ledge 16 between said lugs orears is untreated and lies substantially in alignment with the remainingportions of said ledge.

In the present case the body portion 43 of the bumper block is providedwith the downwardly and endwise projecting lugs 44 and 45 which extendthrough the openings 41 and 42 so as to lock the bumper block in placeon the ledge. Furthermore these downwardly and endwise extending lugs 44and 45 find direct support on the ears 39 and 40 so that the headportion of the bumper block is directly supported throughout its entirelength.

In the present case also the bumper block is provided with thedownwardly extending lip or skirt 46 which slightly overlies the flange17 of the door pillar.

The construction shown in Figures 10, 11, and 12 is similar to that ofFigures 8 and 9, but in the present case the lugs or ears 89 and 40 areeliminated and the lugs 44 and 45 on the bumper block are not affordedsupport thereby.

In the present case also the lip or skirt 47 is carried down asubstantial distance over the face of the inwardly extending flange 17;and there is provided an undercut lug or button 48 which is forcedthrough an opening 49 of the flange 17 so as to lock the lip or skirtthereto.
